Detailed Description

Qt includes.

This class will draw "knobs" at the verticies of the line symbol attached to this drawer. The knob size is part of the DtLineSymbol and the drawing will be centered around the point

Member Function Documentation

virtual bool DtVertexDrawer::draw	(	QPainter &	paint,
		const DtSymbol *const	symbol
	)		const [virtual]

draws the specified symbol on a device.

The symbol must be of a DtLineSymbol type or nothing will be drawn.

Returns:

true if successful, false otherwise.

Implements DtSymbolDrawer.

virtual bool DtVertexDrawer::draw	(	QPainter &	paint,
		const DtSymbol *const	symbol,
		bool	preTransparent
	)		const [virtual]

If preTransparent is true, draw knobs in black if symbol is going to be a transparent draw so this drawer can fill in after.

virtual QSize DtVertexDrawer::calcBBox

(

const DtSymbol *const

symbol

)

const [virtual]

Calculate the drawn size of this symbol.

The symbol must be of a type this drawer can recognize.

Implements DtSymbolDrawer.

const [virtual]

virtual void DtVertexDrawer::drawKnob	(	QPainter &	paint,
		const QPoint &	pnt,
		int	iKnobSize
	)		const [protected, virtual]

Switches on myKnobStyle to draw knob of particular kind.

virtual void DtVertexDrawer::drawSquareKnob	(	QPainter &	paint,
		const QPoint &	pnt,
		int	iKnobSize
	)		const [protected, virtual]

virtual void DtVertexDrawer::drawCircleKnob	(	QPainter &	paint,

		int	iKnobSize
	)		const [protected, virtual]

virtual bool DtVertexDrawer::endTransparentDraw	(	QPainter &	paint,
		const DtSymbol *const	symbol
	)		const [protected, virtual]

Called after transparent draw is finished if symbol wants to draw transparently.
